rgbif is an R package from rOpenSci that allows searching and retrieving data from GBIF. rgbif wraps R code around the GBIF API to allow you to talk to GBIF from R and access metadata, species names, and occurrences.
Installing the package in R is simple:
> install.packages("rgbif")
Once installed, rgbif allows you to easily
- get data for single occurrences
- retrieve multiple occurences
- search for taxon names
- generate maps of occurences
Full functionality is described in the rgbif tutorial. The rgbif package is also part of the SPOCC Species Occurrence Data suite, that provides access to occurrence records from multiple databases.
Citing data retrieved via rgbif
Note: GBIF recommends using a derived dataset for citing data obtained using synchronous API calls as used by rgbif in occ_data() and occ_search().
For data obtained using the occ_download() routes, gbif_citation() can be used to retrieve the DOI.
The rgbif library includes a function, gbif_citation(), that will help you properly cite the data downloaded from GBIF. To use, simply pass either a single occurrence key, a dataset key, or the results of a call to the occ_download_get functions.
Examples:
Write CSV file containing summary of datasets to use with the Derived Dataset tool
> myData<-occ_data(taxonKey=10709636)
> datasetCounts<-myData$data %>% count(datasetKey, sort=TRUE)
> write.table(datasetCounts, "~/derivedDatasetCounts.txt",col.names=FALSE, row.names=FALSE,sep=",")
Get citation for a single occurrence, passing the occurrence key as an argument
> gbif_citation(x=1265576727)
